The circumference of a grapefruit is 4π cm. find the surface area of the grapefruit. express your answer in terms of π. a) 16 pie cm2 b) 32 pie cm2 c) 64 pie cm2 d) 72 pie cm2

We find radius first:
 C = 2 * pie * r
 r = C/(2 pie) = 4 pie cm / (2 pie) = 2 cm
 Now we find surface area: A = 4r˛ = 4 (2)^2 = 16 pie cm2
  Hence the surface area of the grapefruit fruit is 16 pie cm2.
